Coronavirus: A letter from our Chief Medical Officer,
Scott Anderson, MD

Dear Members,

As many of you are already aware, to date the FDA has authorized three COVID-19 vaccines for distribution in the United States that have been deemed generally safe and highly effective in clinical trials – the Pfizer-BioNTech (BNT162b2), Moderna (mRNA-1273) and the Johnson and Johnson (JNJ-78436735).

At this time, the Pfizer vaccine is widely available for all Members aged 12 and older, and the Moderna and J&J vaccines are available for those aged 18 and older.

Although there was a temporary pause on immunizations with the J&J vaccine due to an exceedingly small number of certain types of blood clots that may have been associated with the vaccine, follow-up studies have shown that the risk of developing such serious side effects is extremely low. To put things in perspective, about 15 people out of about 8 million receiving the J&J vaccine got rare blood clots, which is approximately only 0.0015% of all people receiving the vaccine. In contrast, the risk of contracting COVID-19, being hospitalized, or having a serious outcome from getting the virus is exponentially higher. Based on the risk: benefit analysis, the J&J vaccine has been appropriately re-authorized for distribution to the general public.

As of April 25, 2021, 4,228,785 doses of all types of vaccine had been administered to Wisconsin residents, with just over 43% receiving at least one dose and almost 32% completing their vaccine series. People are considered fully vaccinated:

  • 2 weeks after their second dose in a 2-dose series, such as the Pfizer or Moderna vaccines, or
  • 2 weeks after a single-dose vaccine, such as Johnson & Johnson’s Janssen vaccine

Though the cases of COVID have rapidly dropped in the state, and we are seeing some restrictions on gatherings and travel cautiously being lifted – especially for vaccinated individuals – it is important to realize that we’re still in the middle of a pandemic, and nothing has changed regarding recommendations for social distancing and wearing a mask in many public settings – even for vaccinated individuals.

There has obviously been tremendous progress since our last communication – but we still have a lot of work to do in order to get that number above 70% to obtain herd immunity. So, if you are eligible to receive a COVID vaccine, but have not yet done so, we strongly encourage you to find your nearest vaccination site here: .

We will continue to monitor the vaccine rollout and the progress made on immunization status through the WI DHS and CDC. We have added a link to timely, updated vaccine information and encourage you to learn more about the COVID-19 vaccines, including answers to frequently asked questions (FAQs) here:

Thanks for doing your part in helping to continue this forward momentum in the fight against COVID. As always, if you have specific questions about how your own health history may potentially affect your vaccination status, please contact your health care provider.

Stay safe and healthy,

Scott Anderson, M.D.
