Dr. Siu,
      
      In my opinion, your patient should receive her second COVID-19
      vaccine but delay its administration by 90 days.
      
      Current CDC recommendations are:
      
      1.    Anyone who acquired a COVID-19 infection should get the
      COVID-19 vaccine since it can not be assumed that every victim
      will develop a significant immune response from their infection. 
      However, CDC also has stated that it is very likely that most
      COVID-19 victims will have at least 3-6 months of immunity
      following their infection.
      2.    Anyone who has acquired a COVID-19 infection should wait 90
      days before receiving a COVID-19 vaccine to avoid a robust
      reaction to the mRNA vaccine (especially the Moderna vaccine) from
      the presence of high levels of circulating antibodies following a
      natural infection.
       
      That being said, there has been some discussion among public
      health experts that a single dose of a COVID-19 vaccine may be
      sufficient for those people who naturally-acquired a COVID-19
      infection.
      
      Finally,  due to the "immune escape" property in the COVID-19
      variants, there is currently concern among public health experts
      that a modified COVID-19 vaccine "booster" will also be needed for
      the general population in the future.
       
      I hope this is helpful.

      Subject: [MCOH-EH] Second dose
      
      I have a nurse who developed COVID 2 days after the first dose.
      She has now recovered. Should she get the second dose?
      Thanks.
