People who have received a COVID-19 vaccine and a booster shot were more likely to end up in a hospital when infected with BA.5 than BA.2, according to a new study.
Researchers in Portugal found that BA.5 cases among the group had 3.4 times higher odds of hospitalization when compared to BA.2 cases.
Both BA.2 and BA.5 are subvariants of Omicron, a SARS-CoV-2 strain. SARS-CoV-2, also known as the CCP (Chinese Communist Party) virus, causes COVID-19.
Those who were boosted did appear to be better off than those who only received a primary vaccination series.
The protection against hospitalization for a primary series was estimated at 62 percent against BA.2 but just 22 percent against BA.5. The protection from a booster was 93 percent against BA.2, but dropped to 77 percent against the newer subvariant, which is dominant in many countries around the world….
