Speak out on behalf of the voiceless and for the rights of all who are vulnerable. -Proverbs 31:8
After working five 12-hr shifts this week, I was one of the fortunate people to receive the Pfizer COVID-19 vaccine. I choose to receive this vaccine for the return of social gatherings, hugs, concerts, game days, to protect those who are immunocompromised, and to relieve the strain on the healthcare system.
Any new medication or vaccine does have some risks and concerns. After speaking with multiple hospitalists and doing my own research, I am hopeful for better days to come.
What is special about an mRNA vaccine?
- mRNA vaccines create the same protein (spike protein) that is on the SARS-CoV-2 in our bodies so that we can produce antibodies that will fight an infection if we are infected.
- This differs from the flu vaccine which is an inactivated form of the virus. This is not the case with the COVID vaccine- you cannot get COVID by simply taking the vaccine.
How is this safe when developed so quickly?
- Many people, including myself, have been hesitant to accept a vaccine that has been developed so quickly. However, I have learned that scientists have been familiar with mRNA vaccines for years. Once COVID hit, these scientists were able to identify the spike protein on the actual virus and create that same protein into a vaccine for our protection.
How is it administered?
- The vaccine is an intramuscular injection like the flu vaccine and is administered in 2 doses either 21 days apart (Pfizer) or 28 days apart (Moderna).
Considerations/Unknowns
- It is unknown how long natural immunity will last for someone who has already had the COVID-19.
- mild s/e include pain at the injection site, muscle aches, fatigue, h/a, chills, joint pain, and fever. These were more common with the second dose than the first.
What is vaccine efficacy?
- A vaccine is shown to be effective if it reduces the chance of becoming seriously ill.
- Pfizer has shown 95% effectiveness, meaning that 95% of people will not become seriously ill if infected with the virus. This is actually wonderful, considering the flu vaccine is at most around 50% effective.
- it is unknown whether the vaccine reduces transmissibility- continue to wear masks!
I hope this relieves some concerns about the vaccine. I believe in the science and pray for a happier and healthier 2021.
Until next shift,
Shania
