The BA.5 variant has now become the most dominant and transmissible strain of COVID-19 in the U.S., according to the Centers For Disease Control and Prevention. The number of people catching the BA.5 variant of COVID-19 continues to grow, causing some reinfections.

The omicron variant was discovered in November 2021 in Botswana, and was considered more dangerous than the delta variant. With new variants spreading in the U.S. and around the world, there is still much to learn about the COVID-19 virus since its beginning.

A preprint study suggests that people who were vaccinated and boosted have decreased chances of neutralizing the BA.5 variant.

How transmissible are the new omicron variants? How vulnerable are people to reinfection? What is the level of vaccine efficacy on new variants? Are more boosters needed to fight the variants? How long does reinfection remain?
