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?


COVID super-immunity: one of the pandemic’s great puzzles


15 Oct 2021

People who have previously recovered from COVID-19 have a stronger immune response after being vaccinated than those who have never been infected. Scientists are trying to find out why.


If You’ve Had Covid, Do You Need the Vaccine?


12 Oct 2021

So-called natural immunity varies from patient to patient, scientists say. Immunization is still the best choice after recovering from the disease.

Association of Mask Mandates and COVID-19 Case Rates, Hospitalizations, and Deaths in Kansas


23 Jun 2021

This study examined the association between mask mandates in Kansas counties and COVID-19 cases, hospitalizations, and deaths. The Kansas executive order that took effect on July 3 was adopted by only 15 counties, and 68 counties did not have a mandate through October. A second mask mandate order took effect on November 25, and 40 additional counties adopted it.




COVID-19 Vaccination of Health Care Personnel as a Condition of Employment A Logical Addition to Institutional Safety Programs


08 Jun 2021

The consequences of the SARS-CoV-2 pandemic have been far-reaching, particularly among health care personnel (HCP) and within health care settings. HCP have been directly affected, sustaining occupationally acquired COVID-19 infections, and indirectly through a substantial alteration in health care delivery. With the advent of highly effective and safe SARS-CoV-2 vaccines, case rates and hospitalization rates are declining, and the promise of a return to some semblance of pre–COVID-19 health care is growing. Recently, several medical centers have announced a requirement for SARS-CoV-2 vaccination of all HCP (allowing for medical and religious exemptions), and the impending licensure of the mRNA SARS-CoV-2 vaccines (following the previous Emergency Use Authorization [EUA]) will move many other centers to consider a similar policy. A recent outbreak in a skilled nursing facility attributed to an unvaccinated HCP member clearly illustrates the risk unvaccinated HCP can pose to their patients and other HCP.1




We are scheduling training with them this week on how to generate the report.


07 Jun 2021

The Centers for Disease Control and Prevention (CDC) recently issued guidance that fully vaccinated individuals can safely remove masks and end social distancing in most indoor settings.1 Educational facilities and businesses are faced with whether and how to differentiate between vaccinated and unvaccinated individuals, including requiring proof of vaccination. Mandatory vaccination has historically served as a tool to reach and sustain high immunization coverage and to prevent transmission in K-12 schools, colleges/universities, and health care facilities. Vaccine mandates could extend to workers and customers in businesses to ensure safer environments. This Viewpoint examines the epidemiologic, public health, and legal considerations for mandatory SARS-CoV-2 vaccinations in each setting.




Mix-and-match COVID vaccines trigger potent immune response


19 May 2021

Preliminary results from a trial of more than 600 people are the first to show the benefits of combining different vaccines.




Even Partial COVID-19 Vaccination Protects Nursing Home Residents


17 May 2021

A CDC analysis has shown that a single dose of the Pfizer-BioNTech COVID-19 vaccine protected medically vulnerable nursing home residents as well as it did general adult populations that were evaluated in other efficacy and effectiveness studies.
