Moderna COVID-19 booster may protect against variants


03 Nov 2021

At a Glance A booster of the Moderna COVID-19 vaccine increased levels of neutralizing antibodies against all variants of concern in a primate study. The findings suggest that COVID-19 boosters not only lengthen immunity but help broaden and strengthen the immune response.


DC Recommends Pediatric COVID-19 Vaccine for Children 5 to 11 Years


02 Nov 2021

Today, CDC Director Rochelle P. Walensky, M.D., M.P.H., endorsed the CDC Advisory Committee on Immunization Practices’ (ACIP) recommendation that children 5 to 11 years old be vaccinated against COVID-19 with the Pfizer-BioNTech pediatric vaccine.

Breakthrough Infections Occur in Those with Lower Antibody Levels, Israeli Study Shows


26 Oct 2021

To see how COVID-19 vaccines are working in the real world, Israel has provided particularly compelling data. The fact that Israel is relatively small, keeps comprehensive medical records, and has a high vaccination rate with a single vaccine (Pfizer) has contributed to its robust data collection. Now, a new Israeli study offers some insight into those relatively uncommon breakthrough infections. It confirms that breakthrough cases, as might be expected, arise most often in individuals with lower levels of neutralizing antibodies.


Coronavirus (COVID-19) Update: FDA Takes Additional Actions on the Use of a Booster Dose for COVID-19 Vaccines


20 Oct 2021

Today, the U.S. Food and Drug Administration took action to expand the use of a booster dose for COVID-19 vaccines in eligible populations. The agency is amending the emergency use authorizations (EUA) for COVID-19 vaccines to allow for the use of a single booster dose as follows: The use of a single booster dose of the Moderna COVID-19 Vaccine that may be administered at least 6 months after completion of the primary series to individuals: 65 years of age and older 18 through 64 years of age at high risk of severe COVID-19 18 through 64 years of age with frequent institutional or occupational exposure to SARS-CoV-2


COVID-19 Vaccines Protect the Family, Too


19 Oct 2021

Any of the available COVID-19 vaccines offer remarkable personal protection against the coronavirus SARS-CoV-2. So, it also stands to reason that folks who are vaccinated will reduce the risk of spreading the virus to family members within their households. That protection is particularly important when not all family members can be immunized—as when there are children under age 12 or adults with immunosuppression in the home. But just how much can vaccines help to protect families from COVID-19 when only some, not all, in the household have immunity?
