COVID variants and vaccines. Studies are also ongoing to monitor the variants and their implications for the COVID-19 vaccines. “Every time there’s a new variant, you take people’s blood who’ve been vaccinated and see if their antibodies recognize this variant of SARS-CoV-2 as well as the original. That provides the first clue,” said ...
