Will taking antibiotics interfere with the vaccine?

No. You must take all prescribed antibiotics as prescribed.

Why does the second vaccine cause more of a reaction than the first shot? Has it been made more powerful or different?

The second dose of the vaccine is actually exactly the same as the first. The reason more people respond to the second shot is that their immune systems were primed by the first dose. That’s how your immune system works. In general, it is expected that the response to the second shot will be stronger. But in terms of a two-dose vaccine, that translates to more potential side effects the second time around.


I have had the COVID-19 virus and have recovered. How long will I have to wait to get the vaccine? I was told 90 days but recently read online that they now say 6 months. How long do I have to wait?

The reason for the wait is that the vaccine was scarce. People with a recent infection have been protected for at least 90 days and can wait to be vaccinated. Once the vaccine is more widely available, you don’t have to delay it.

The CDC said you can get vaccinated as soon as you recover and your quarantine period is over.

I received the first dose of the Moderna vaccine without any significant event. Eight days after the vaccine, my arm became warm, red, itchy, and swollen around the injection site. The next day I had a red, swollen spot again. The third day another red, swollen spot and the small spots on the second day got bigger and mixed into one. What causes this, what should I do about it and do I get the second dose?


This is a documented rare reaction called ‘Moderna Arm’. It appears to be a delayed hypersensitive skin reaction. It can be treated with ice and antihistamines.

There is a risk that you will have the same response to your second dose, but it is still recommended to fully protect that second injection.
