Hi Rosemary, and thanks for your post - you've posed good questions.
My wife and I have each had both vaccination injections (Pfizer), as recommended, 3 weeks apart. We then took the booster (3rd injection) about 6 1/2 months after that. Now, we are planning to have the second booster (4th) injection in the next week or so. Of course, besides the public service announcements recommending this, we made certain this was the right thing (for us) to do by speaking with our primary physician.
Before you actually decide not to get the booster, you may want to discuss this with your physician.
To complete my answer for your concerns - we have taken the flu shot every year since it was offered - we never missed a flu vaccine injection.
Neither of us have taken the pneumococcal pneumonia injection we don't feel the need and again, our doctor concurs.
What are your reasons for thinking of declining the booster shot and, for not taking either the pneumonia shot or the annual flu shots?
Is there anything further you can share with the community at this time?
Wishing you well,
