Infections which saw a high number of new cases and deaths on thursday. north korea has reportedly rejected donations of the astrazeneca vaccine due to concerns over its potential side effects, according to a south korean think tank. north korea has yet to confirm a single case of covid i9, a claim long questioned by analysts. in the united states, there s been a clash between vaccine makers and health officials over whether the public need a third vaccine jab, or booster shot. last night pfizer said it would seek approval for a third dose, amid concerns over the rapidly spreading delta variant. the centers for disease control, the food and drug administration, and the who have all weighed in, saying a third jab isn t needed, or not right now. pfizer has been developing a booster treatment as a way to strengthen antibodies which fade over time and guard against new, highly ....
Pfizer say they re going to be seeking this emergency approval regardless. what s involved in the process? well, the process is really quite robust. they all submit all of their data to the fda, the fda will massage it for a while and then there will be a select committee that is not part of the fda but advises the fda, that will then massage it further and will make a recommendation. and almost always, but not always, the fda follows that select committee s recommendation. then it goes to the cdc where the cdc will massage the data. they have another committee that s independent of the cdc, that advises the cdc, called acip they ll do the same thing and, ultimately, give their blessing, or not, to the cdc. so it s somewhat serpentine, how they re going to get there. this comes amid rising cases of the delta variant causing concern here in the uk, also across large parts of asia. ....
And now we re getting the same phenomenon. so we re just always a few months behind the uk with these variants. but what we re going to continue to see until we get herd immunity in this planet notjust in one country or two countries, but on this planet we re going to see, continue to see human beings getting infected and producing new variants, and some of these variants ultimately may escape the immunity we get from vaccines. you mentioned the global immunity. there s this discussion about third doses, but huge parts of the world, people haven t even had their first dose yet. yes, yes. there is an irony there, isn t there. pfizer s talking about giving people here a third dose and we ve got so many billions of people not vaccinated at all. it s been saddening and it s a good argument if there s that much excess vaccine, perhaps we would be better off all of us would be better off if we used that vaccine to get more people vaccinated in other parts of ....
Contagious versions of covid. well, earlier i spoke to drjohn swartzberg, professor emeritus of the school of public health and an expert on vaccines and infectious diseases at the university of california berkeley. i asked whether a third vaccine dose made sense in helping to gain greater protection against the virus. if a little bits good, a lot must be better. of course, that doesn t hold for a lot of things, particularly medicines. you know, pfizer s idea, that people need a third dose, is curious. they didn t complement that with any, releasing any data to support their argument, and frankly there is no data that i m aware of that says that people need a third dose at this point. it s perfectly possible that months from now immunity may wane and we may need a third dose, but right now there s just no evidence for that. i think the who and the cdc and the fda are all correct. ....
