 First Lady Jill Biden tested positive for Covid-19

First Lady Jill Biden tested positive for Covid-19 on Monday, the White House said, while she and her husband President Joe Biden are on a family vacation in South Carolina.

Everyone is asking about the effectiveness of covid vaccines that were given to citizens. If vaccines are really effective why does lady Biden get affected?

Some specialists are saying that this would have been so much worse if she wasn't vaccinated four times in one year against a mild respiratory virus with a 99.996% survival rate.
