The Omicron variant of COVID-19 is highly contagious and has spread rapidly across the world. While vaccinated people are still contracting the virus, data from various countries shows that they are significantly less likely to be hospitalized or die from the virus compared to unvaccinated people. For example, in Spain, the mortality rate among unvaccinated individuals aged 70-80 was five times higher than that of vaccinated individuals. Similarly, in Italy and Switzerland, the probability of hospital admission for the unvaccinated in the 60-79 age group was ten times higher. In the United States, data showed that 54% of people hospitalized for COVID-19 over the age of 65 were unvaccinated, despite only 12% of people in this age group being unvaccinated overall. However, it is important to note that the protection offered by vaccination against Omicron declines over time, and a booster shot is necessary to strengthen protection and reduce the chances of severe disease and hospitalization.

What You'll Learn
Vaccinated people are less likely to be hospitalized with Omicron
The Omicron variant of COVID-19 is highly contagious and transmissible, and it has spread rapidly across the world. While Omicron can infect vaccinated individuals, data shows that vaccinated people are less likely to be hospitalized with severe illness. Vaccination continues to offer significant protection against severe disease and hospitalization, even with the emergence of the Omicron variant.
Vaccine Effectiveness and Hospitalization Rates
Partial data from Spain and extensive analysis from the United Kingdom demonstrate that vaccinated individuals are at a significantly lower risk of hospitalization and death from COVID-19, including the Omicron variant. In Catalonia, Spain, the mortality rate among unvaccinated individuals aged 70 to 80 was five times higher than their vaccinated counterparts. Similarly, in Italy and Switzerland, the probability of hospital admission for the unvaccinated in the 60-79 age group was ten times higher.
Impact of Booster Shots
The protection offered by COVID-19 vaccines against Omicron may wane over time. However, booster shots play a crucial role in strengthening protection and reducing the chances of severe disease and hospitalization. Studies have shown that vaccine effectiveness against symptomatic Omicron infections decreases over time, but a booster shot can enhance protection. For individuals over 65, COVID-19 vaccines are approximately 90% effective in preventing severe disease and hospitalization after a booster dose.
Reducing Risk and Severity
Vaccination, especially when coupled with booster shots, remains the most effective way to prevent severe illness and hospitalization due to Omicron. Additionally, masking, physical distancing, and following isolation guidelines when infected contribute to reducing the spread and severity of Omicron infections. While vaccinated individuals may still be infected with Omicron, they are likely to experience milder symptoms or even asymptomatic cases, reducing the strain on healthcare systems.

Vaccinated people are less likely to have severe Omicron symptoms
While the Omicron variant of COVID-19 is capable of infecting vaccinated individuals, studies have shown that vaccinated people are less likely to develop severe symptoms. Vaccinated people are also less likely to be hospitalized due to COVID-19 and tend to exhibit mild or asymptomatic cases. The effectiveness of two doses against symptomatic infections drops significantly after six months, and a booster shot is required to strengthen protection.
Data from the US shows that the percentage of people hospitalized due to COVID-19 is disproportionately unvaccinated and not boosted. CDC data shows that 54% of people hospitalized for COVID-19 over the age of 65 are unvaccinated, despite only 12% of people in this age group being unvaccinated overall. Just 8% of patients hospitalized in this dataset were vaccinated and boosted. The data confirms that vaccination and boosting continue to protect against severe illness and hospitalization, even during the Omicron surge.
Similar trends are observed in other countries. In Spain, partial data and analysis in the UK show that vaccinated individuals are at a much lower risk of hospitalization and death from COVID-19. In Catalonia, the mortality rate among unvaccinated individuals aged 70-80 is five times higher than that of vaccinated individuals. In Italy, the probability of hospital admission is ten times higher for the unvaccinated in the 60-79 age group, a figure also observed in Switzerland.
In Canada, while the number of hospitalizations is higher among fully vaccinated people, this is due to the high vaccination rates in the province. Unvaccinated people make up a much larger proportion of hospitalizations than their proportion of the overall population. Vaccination status also plays a role in the number of deaths, with the unvaccinated population making up almost 19% of all deaths in the province.
Overall, while vaccinated people can still contract COVID-19, they are less likely to develop severe symptoms or require hospitalization. Vaccination, especially with a booster shot, provides significant protection against the Omicron variant and helps reduce the risk of severe illness and hospitalization.

Unvaccinated people are more likely to be hospitalized with Omicron
During the Omicron wave, unvaccinated people were more likely to be hospitalized with COVID-19 than those who were vaccinated. According to data from Los Angeles County, COVID-19 cases were 12.3 times higher for the unvaccinated compared to boosted individuals, and hospitalizations were 83 times higher. Furthermore, the Centers for Disease Control and Prevention (CDC) reported that unvaccinated individuals were 23 times more likely to require hospitalization than those who were fully vaccinated and boosted.
This disparity in hospitalization rates is not limited to a specific region. In Canada, for instance, the unvaccinated population made up almost 19% of all COVID-related deaths in the province. Despite higher overall numbers of hospitalizations among vaccinated individuals in areas with high vaccination rates, the unvaccinated still represented a larger proportion of hospitalizations relative to their share of the population.
The risk of severe illness and hospitalization from COVID-19 can be significantly reduced through vaccination and booster shots. Health experts strongly encourage everyone who is eligible to get vaccinated and boosted, as this provides the best protection against the virus. Additionally, masking and physical distancing are recommended as additional layers of protection to prevent hospitalization and severe illness.
While the vast majority of vaccinated individuals are well-protected against severe illness caused by Omicron, there are still rare cases of vaccinated people being hospitalized. However, it is important to note that these individuals represent a tiny proportion of the overall vaccinated population. The available data and expert opinions emphasize that vaccines are highly effective in preventing severe disease and reducing the need for hospitalization, especially when combined with other precautionary measures.

Vaccinated people can still spread Omicron
While COVID-19 vaccines have been proven to protect against severe illness, hospitalization, and death, vaccinated individuals can still contract and spread the virus, including the Omicron variant. Vaccinated people are less likely to spread Omicron than unvaccinated people, but the risk remains.
The Omicron variant, which emerged in late 2021, is highly contagious and spread rapidly worldwide. Studies have shown that Omicron generally does not make people as sick as the previous Delta variant, but its high transmissibility has strained healthcare systems.
Vaccinated individuals who contract Omicron may experience milder symptoms or even be asymptomatic, making it difficult to distinguish between a mild case of COVID-19 and another illness. As a result, they may unknowingly spread the virus to others before realizing they are infected. This underscores the importance of regular testing, even among vaccinated individuals, to help curb the spread of the virus.
Vaccination status also plays a role in hospitalization rates. While fully vaccinated individuals may be hospitalized with COVID-19, they often represent a small proportion of overall hospitalizations. This is because unvaccinated individuals are at a higher risk of severe illness and death from COVID-19 and, therefore, have higher hospitalization rates.
To summarize, while vaccinated people are less likely to spread Omicron than unvaccinated people, they can still transmit the virus. The risk of transmission and severe illness is lower for vaccinated individuals, but it is not eliminated. Regular testing, masking, physical distancing, and staying up-to-date with vaccinations are essential to protecting oneself and others from COVID-19 and its variants.

Vaccinated people are less likely to die from Omicron
While the Omicron variant of COVID-19 is capable of infecting vaccinated individuals, data shows that vaccinated people are less likely to die from the virus. Vaccinated people are also less likely to develop severe complications and be hospitalized.
In Spain, partial data collected shows that the mortality rate among unvaccinated individuals aged 70-80 is five times higher than that of vaccinated individuals. Similarly, in Italy, the probability of hospital admission is ten times higher for the unvaccinated in the 60-79 age group. In the UK, the Health Security Agency (HSA) has analyzed more than half a million Omicron infections, and their results confirm that vaccines continue to protect those who are fully vaccinated, especially against severe disease.
In Canada, health officials have noted that while the number of hospitalizations is higher among fully vaccinated people, this is due to the high vaccination rates in the province. Unvaccinated people make up a much larger proportion of hospitalizations than their proportion of the overall population. Vaccination status also comes into account when considering the number of deaths. In one province, the unvaccinated population made up almost 19% of all deaths.
In the United States, data from the CDC shows that 54% of people hospitalized for COVID-19 over the age of 65 are unvaccinated, despite only 12% of people in this age group being unvaccinated overall. The data also shows that vaccination and boosting continue to protect against severe illness and hospitalization during the Omicron surge.
While the protection provided by COVID-19 vaccines against the Omicron variant may be lower compared to other variants, getting vaccinated still teaches your body how to recognize and fight the virus. A booster shot further increases protection, reducing the chances of severe disease and hospitalization.
