It is not obvious we need booster vaccinations. There's simply not enough data yet to call this "obvious". Even "likely" is a stretch. Time will tell how long effective immunity lasts, but we absolutely do not know that number yet. EDIT: To be fair, it is at least likely that high-risk individuals may need boosters. Israel is already distributing them. But the idea that we will need an annual COVID shot, or that most people will need any additional shots at all, is entirely speculative. The annual shot idea is especially dubious because I think people infer this from the flu, which mutates far more rapidly than this coronavirus.

That's correct, so far. It appears that humans who have been vaccinated with an mRNA vaccine still have a strong immune response to Delta variant. In fact, far better of an immune response than people who were infected with a previous variant.

  I am not in any way saying the intramuscular do not protect the internal body tissues against variants. I am saying that it's important to protect against mucosa infection too to prevent spread and that requires intranasal vaccination.

Effective immunity against current variants isn't too likely to be an issue, but new variants that circumvent that immunity seem pretty likely to me seeing as we're already seeing this to some extent with the Delta variant and we're nowhere near suppressing case levels to the point that we'd slow new variants from emerging.

Big pharma is pushing for boosters before the science. I’m happy that even Congress was skeptical of the claim in the last covid congressional committee discussion.

You only responded to my first sentence. To be clear, what the two sentences mean together is, "It is obvious we need intranasal booster vaccinations." I am not in any way saying the intramuscular do not protect the internal body tissues against variants. I am saying that it's important to protect against mucosa infection too to prevent spread and that requires intranasal vaccination.

>It is not obvious we need booster vaccinations. Of course, but to be fair, I don't expect any EU government to publicly acknowledge that we need a third dose when many EU countries are still struggling to get two doses to everyone, let alone a third. Like how at the beginning of the pandemic in early 2020 the governments said that masks are not useful at protecting against the virus in order to prevent the general population from scalping and hoarding masks that were needed for medical personnel instead, and later did a 180 on that decision, making masks mandatory when mask production supplies caught up with the demand. Such decisions are not 100% driven purely by medicine/science but also economics/politics.

The Israeli data is showing that the Pfizer's vaccine effectiveness against infection is waning over time among the fully vaccinated. * Vaccinated in January: 16% protection * Vaccinated in February: 44% protection * Vaccinated in March: 67% protection * Vaccinated in April: 75% protection https://www.timesofisrael.com/israeli-uk-data-offer-mixed-signals-on-vaccines-potency-against-delta-strain/ https://www.timesofisrael.com/israeli-uk-data-offer-mixed-si... See also video from John Campbell about it: https://www.youtube.com/watch?v=wNbs4LCgrcY https://www.youtube.com/watch?v=wNbs4LCgrcY The protection against hospitalisation is about 88% and seems stable over time.
