These boosters are designed to protect against disease caused by the original strain of the SARS-CoV-2 virus, as well as the Omicron subvariants BA.4 and BA.5 (although experts are still learning about their effectiveness against the latest Omicron subvariants). Severity:It did not appear to pose a greater chance of hospitalization or death.

Get the latest COVID-19 news from infectious diseases expert Mark Rupp, MD, including COVID-19 case rates, types of variants circulating and vaccine updates. One explanation was that more than 30 of Omicrons mutations are on the viruss spike protein, the part that attaches to human cells, and several of those are believed to increase the probability of infection. The Centers for Disease Control and Prevention (CDC) cannot attest to the accuracy of a non-federal website. COVID-19 cases, hospitalizations and deaths continue to decline. Many of these variants' mutations have little or no impact on how the virus affects humans. What Are the Symptoms of Omicron? - New York Times But it could have been a lot worse. What is the monster variant of COVID-19? But it has also noted that surges in cases may lead to significant increases in hospitalizations and deaths, as they did during the variants spread in the beginning of 2022, when the estimated death rates went as high or higher than they were at the time of the Delta variant surge in the previous autumn.
