Delaware's Second Dose Vaccine Plan

The state is committed to ensuring all Delawareans receive their second dose by Day 42, unless federal guidance recommends otherwise. While the science shows that the first dose of COVID-19 vaccine provides 52% to 80% protection DPH also believes it’s important to get Delawareans their second doses to be fully vaccinated. Getting your second shot will also maximize the impact of a booster shot, if one is needed down the road.

We know some people are reluctant to get the second dose of a vaccine because they’ve heard about side effects that may be unpleasant. We hear you. But the side effects are a sign that your body is gearing itself up to fight a real infection. It’s definitely better than getting COVID! So, plan for it. If possible, plan to stay home. Plan for a movie binge day. Plan to have ibuprofen on hand, and drink lots of water. You may not need any of this, but if it happens, you’ll be ready. It will all be OK. The side effects are temporary. It will all be worth it.

When Should I Get My Second Dose?

It is currently recommended that people receive a second dose as close to the recommended timeframe as possible:

  • Pfizer-BioNTech Vaccine – no earlier than 21 days after the first dose
  • Moderna – no earlier than 28 days after the first dose

You should get your second shot as close to the recommended 3-week or 4-week interval as possible. However, your second dose may be given up to 6 weeks (42 days) after the first dose, if necessary. You should not get the second dose early. There is currently limited information on the effectiveness of receiving your second shot earlier than recommended or later than 6 weeks after the first shot. However, if you do receive your second shot of COVID-19 vaccine earlier or later than recommended, you do not have to restart the vaccine series. This guidance may be updated as more information becomes available.

Where Can I Get My Second Dose?

You should expect to receive your second dose in the same location as your first. It may not be exactly at 21 or 28 days. Some sites may not make second dose appointments in advance. If you are having trouble getting your second dose, email
