Exactly. I trust the recommendations of the pharmaceutical companies that developed the vaccines. They say take both shots.
Who advised you not to do so? It certainly wasn't me. The article that I linked, which began your tirade against "experts" and their suspicious (to you) motives, doesn't advise you not to "take both shots" either. If that's what you want to talk about make your own post about it; you don't need to do it by pretending that your replying to me about something that I never advocated.
Of course, that's one major advantage of the J&J vaccine. It's one and done. It's twice as fast at getting a large number of people fully vaccinated. It requires half the number of syringes, half the amount of vaccine, and the same number of personnel can vaccinate twice the number of people in a given period, reducing the load and burden on them by half as well, over time.
In fairness to those who
have recommended
lengthening intervals between administration of
both doses of other vaccines, the recommendation from vaccine makers for dosage intervals — and the decision by some countries to extend those intervals by a certain number of days in order to deliver more first round doses to affect some degree of protective immunity in a larger set of the population more rapidly — is a calculation made on a limited set of data in
both instances. Until studies on the relative effectiveness of individual vaccines given at varying intervals have been made thru acquisition of more data, the optimum effective intervals and the affect on overall containment and reduction of severity will remain uncertain for some time.
https://www.cdc.gov/vaccines/covid-19/info-by-product/clinical-considerationsInterval between mRNA dosesThe second dose of Pfizer-BioNTech and Moderna vaccines should be administered as close to the recommended interval as possible, but not earlier than recommended (i.e., 3 weeks [Pfizer-BioNTech] or 1 month [Moderna]). However, second doses administered within a grace period of 4 days earlier than the recommended date for the second dose are still considered valid. If it is not feasible to adhere to the recommended interval and a delay in vaccination is unavoidable, the second dose of Pfizer-BioNTech and Moderna COVID-19 vaccines may be administered up to 6 weeks (42 days) after the first dose. Currently, only limited data are available on efficacy of mRNA COVID-19 vaccines administered beyond this window.
