Remember that the jab does not make you immune from the virus, or stop you from transmitting the virus to others. The pfizer jab is not technically a vaccine, it's a pharmaceutical product, and it is effective 9 times out of 10 in blocking symptoms among infected people. It does not have anything to do with immunity. Also remember that once you have taken one company's product, you can't switch to another, even if a better one comes out. So hopefully the pfizer one you've settled on helps block the covid symptoms once you get sick, making the risks and side effects worthwhile. Even better would be not getting sick at all, but apparently that's not an option unless a real vaccine comes along, that actually provides protection from the virus. Nice to hear you're recovering well from the first dose.
