Sorry I had to leave before you woke up. You’re right, it isn’t fair. Please empty the dishwasher today. And brush your teeth. Remember to feed the dog. He will die if no one remembers to do this.

Phase 3 trial of Novavax investigational COVID-19 vaccine opens

28 Dec 2020

The Phase 3 trial of another investigational coronavirus disease 2019 (COVID-19) vaccine has begun enrolling adult volunteers. The randomized, placebo-controlled trial will enroll approximately 30,000 people at approximately 115 sites in the United States and Mexico. It will evaluate the safety and efficacy of NVX-CoV2373, a vaccine candidate developed by Novavax, Inc., of Gaithersburg, Maryland. Novavax is leading the trial as the regulatory sponsor.

Older Adults’ Perspectives on a COVID-19 Vaccine

23 Dec 2020

As of December 4, 2020, cases of novel coronavirus disease 2019 (COVID-19) have topped 14.3 million in the US with nearly 300 000 associated deaths. While mitigation measures such as social distancing, use of face coverings, and avoidance of crowds can help keep case counts in check, a safe and effective COVID-19 vaccine will be essential to ending the pandemic.

Coronavirus Vaccines

02 Oct 2020

Leading COVID-19 vaccine candidates rely on new genetic technologies that have fast-tracked development and testing. This video explains the principles underlying the leading DNA, messenger RNA (mRNA), and viral vector vaccine candidates, and how they might induce immunity to SARS-CoV-2 infection.


Coverage and Estimated Effectiveness of mRNA COVID-19 Vaccines Among US Veterans

06 Oct 2021

Question What was the COVID-19 vaccination coverage and estimated mRNA COVID-19 vaccine effectiveness (VE) among US veterans in the first 3 months following vaccine rollout? Findings In this case-control study including 6 647 733 veterans, 23% of veterans received at least 1 COVID-19 vaccination during the first 3 months of vaccine rollout. VE against infection was estimated to be 95% for full vaccination; estimated VE against COVID-19-related hospitalization was 91%, and there were no COVID-19–related deaths among fully vaccinated veterans. Meaning These findings suggest that early vaccination rollout for veterans was efficient, and estimated VE was high for this diverse US population.

Protection of BNT162b2 Vaccine Booster against Covid-19 in Israel

15 Sep 2021

Background: On July 30, 2021, the administration of a third (booster) dose of the BNT162b2 messenger RNA vaccine (Pfizer-BioNTech) was approved in Israel for persons who were 60 years of age or older and who had received a second dose of vaccine at least 5 months earlier. Data are needed regarding the effect of the booster dose on the rate of confirmed coronavirus 2019 disease (Covid-19) and the rate of severe illness. Conclusions: In this study involving participants who were 60 years of age or older and had received two doses of the BNT162b2 vaccine at least 5 months earlier, we found that the rates of confirmed Covid-19 and severe illness were substantially lower among those who received a booster (third) dose of the BNT162b2 vaccine.

Surveillance for Adverse Events After COVID-19 mRNA Vaccination

03 Sep 2021

Question Are mRNA COVID-19 vaccines associated with increased risk for serious health outcomes during days 1 to 21 after vaccination? Findings In this interim analysis of surveillance data from 6.2 million persons who received 11.8 million doses of an mRNA vaccine, event rates for 23 serious health outcomes were not significantly higher for individuals 1 to 21 days after vaccination compared with similar individuals at 22 to 42 days after vaccination.

Variants of SARS-CoV-2

13 Aug 2021

When a virus develops a new mutation, it is called a variant of the original virus. As viruses spread, they constantly change through mutations to their genetic code. Most mutations in the SARS-CoV-2 genome do not affect the functioning of the virus. However, mutations in the spike protein of SARS-CoV-2, which binds to receptors on cells lining the inside of the human nose, may make the virus easier to spread or affect how well vaccines protect people. Other mutations may lead to SARS-CoV-2 being less responsive to treatments for COVID-19.

Randomized Trial of a Third Dose of mRNA-1273 Vaccine in Transplant Recipients

11 Aug 2021

In organ-transplant recipients, the standard two-dose vaccination strategy for coronavirus disease 2019 (Covid-19) has suboptimal immunogenicity.1 Both patients and health care providers have questioned whether a third-dose booster in transplant recipients would be safe and enhance immune response.2 We performed a double-blind, randomized, controlled trial of a third dose of mRNA-1273 vaccine (Moderna) as compared with placebo (the protocol is available with the full text of this letter at; number, NCT04885907. opens in new tab).
