I have some answers to some questions I have been asked about Covid-19 mRNA Vaccines, Pfizer-BioNTech, and Moderna. Other types of Covid-19 vaccines may be available in the future in the US.
1) Both Moderna and Pfizer-BioNTech mRNA COVID-19 vaccines have Polyethylene glycol (PEG) and a history of allergy to Polyethylene glycol or any polysorbate product is a contraindication to the vaccine.
2) The American College of Obstetrics and Gynecology states pregnant and lactating women can get mRNA Covid-19 vaccines. Messenger RNA is NOT taken up by the genetic material of the person’s immune cells, pregnant woman with Covid-19 have a higher risk of becoming severely ill with Covid-19 and are considered in phase 1 of immunization after healthcare workers. Data of side effects of these mRNA vaccines are being collected. https://www.acog.org/covid-19/covid-19-vaccines-and-pregnancy-conversation-guide-for-clinicians
3) Approved for ages: Pfizer-BioNTech: ages ≥16 years, Moderna: ages ≥18 years
4) A person must wait 3 months after Covid-19 illness or infusion with Covid-19 monoclonal antibody to receive the vaccine.
5) mRNA vaccine can be given at any time after another vaccine, examples; influenza, pneumonia, tetanus, pertussis, or shingles vaccines.
