People ages 6 months through 64 years, and especially males ages 12 through 39 years, may consider getting the 2nd primary dose of an mRNA COVID-19 vaccine (Pfizer-BioNTech or Moderna) 8 weeks after the 1st dose. A longer time between the 1st and 2nd primary doses may increase how much protection the vaccines offer, and further minimize the rare risk of heart problems, including myocarditis and pericarditis.

You may receive a Pfizer booster even if your original vaccination was Moderna or JJ. Booster recommended 5 months after final dose of primary series. 2nd booster 4 months after 1st booster for >50 years old ONLY.

2nd dose is given 3-8 weeks after 1st dose
3rd dose is given at least 8 weeks after 2nd dose
