I personally know MD's that don't recommend the vaccine for recovered patients, pregnant women, and even people on a cocktail of other drugs.
I don't want to take this off track, but just want to point out that vaccines were widely shunned for pregnant women in Dec/Jan, but clinical studies have since shown that the risk is much greater from covid, and the current advice for pregnant women is more as ckmk47 says below,
A doctor I know from the front lines considers pregnancy a 'risk factor' for getting a bad case of covid, (especially in conjunction with other mild risk factors such as mildly obese) and recommends that pregnant women get the vaccine. (not the J&J)
But you raise an interesting issue, that when expert doctors impart their advice, it isn't uniformly adopted by health practitioners. Some may have heard the earlier advice and used it in their practice, and are slow to accept improvements.
One (data-based!) example of this happened with treatment of stomach ulcers. For decades, they were treatment was a bland diet -lots of pudding and ice cream - but in the 1990s, scientists found that a short treatment with antibiotics could cure them. Several years after this became standard treatment, a survey found that many doctors had still not adopted this treatment in their practice. Something about old dogs and new tricks.
So there are really two kinds of disagreements: One is the changes that occur over time, as scientific knowledge evolves, and the experts learn more about the disease and its treatment, so effectively disagree with their own prior advice. The other is the changes that occur over geographical space, as personal physicians in different areas interpret that advice and use it differently, so disagree with other physicians advising other patients.
Also again, even now you have tons of MD's disagreeing on so much. With school starting each school has their MD they consult with, some require weekly testing, some require masks, some require nothing, some require one test after vacations, etc etc. There is no one answer to many problems like people want there to be, therefore they decide to just phooey the whole system, as it seems no one agrees on what to do anyway.
This is an example of that second kind of disagreement. On the one hand, it makes sense that MDs would give different advice to different schools - The schools may differ in number of kids/class, size of the rooms, ventilation, length of classes, and much more, so they really do need customized application of the general advice to their particular situation. On the other hand, different MDs may be more knowledgeable than others.
But here too, I don't accept those who "just phooey the whole system". At least in our community, we say AYLOR, and don't give it all up just because different LORs disagree.
