Even if your second shot is delayed by several weeks, you do not have to start over. Get your second shot as soon as you can.

My husband and I are in the 65+ age group trying to get the vaccine. Now that restaurants and other venues are opening up with unlimited/limited capacity on March 1st, can we go to these places and not be too concerned about getting covid? – FloJo

I would not change your behavior at all until you are both fully vaccinated. But the vaccines, while highly effective, are not 100% effective so there is still a small chance you could get COVID-19. You’ll have to weigh the risks and benefits of going out and about. I would continue to wear a mask and socially distance wherever possible. Indoor dining is risky because you have to take your mask off for some period of time, so I might think twice about doing that. Dine outdoors whenever possible.

If you’ve received 2 doses of the vaccine, do you think it’s safe to go away on vacation? I’m thinking about going to Florida at the end of April, but not 100% sure if it’s the right decision. – Priscilla

You will be considered fully vaccinated once you’re 2 weeks out from your second dose. That said, while highly effective, the vaccines are not 100% effective so there is still a small risk that you could get sick from COVID-19. That’s a risk that you may be willing to take to get away. Just please continue to be careful while you’re traveling. Some states are not as conscientious about mask-wearing and social-distancing. so stay on your guard.
