Last Saturday, my wife and I got the booster vaccine for the COVID-19. Right now, I’m fine, but she has had a reaction to the shot. She has a high fever and is feeling terribly bad. So, she stayed home on Sunday and left work, early on Monday. She is still not back to normal today. It can’t be helped. However, I think that the booster is necessary to visit the US this summer. If we have a chance, we’d like to catch some Major League Baseball games in LA this summer.
