What to Expect After Getting a COVID-19 VaccineCOVID-19 vaccination will help protect you from getting COVID-19. You may have some side effects, which are normal signs that your body is building protection. These side effects may affect your ability to do daily activities, but they should go away in a few days. If you have pain or discomfort, talk to your doctor about taking an over-the-counter medicine, such as ibuprofen or acetaminophen. Common side effects include pain and swelling in the arm where you receive the shot.
Improving Ventilation in Your Home
Staying home with only members of your household is the best way to keep COVID-19 out of your home. However, if a visitor needs to be in your home, improving ventilation (air flow) can help prevent virus particles from accumulating in the air in your home. Good ventilation, along with other preventive actions, can help prevent you from getting and spreading COVID-19. There are ways you can improve ventilation in your home. Use as many ways as you can (open windows, use air filters, and turn on fans) to help clear out virus particles in your home faster.
New COVID-19 Variants
Information about recently discovered COVID-19 variants is rapidly emerging. Scientists are working to learn more about how easily they might spread, whether they could cause more severe illness, and whether currently authorized vaccines will protect people against them. At this time, there is no evidence that these variants cause more severe illness or increased risk of death. CDC, in collaboration with other public health agencies, is monitoring the situation closely.
