Is it not a consequence of the EU comission dithering on their order meaning that Pfizer had to ramp up production significantly at late notice?
Got to find that angle.

Partly, but a bigger issue is probably the fact that Astra Zeneca was expected to be approved by now. I don't think Pfizer anticipated being more or less the only high volume supplier in the EU at this point.Is it not a consequence of the EU comission dithering on their order meaning that Pfizer had to ramp up production significantly at late notice?

Seems like a fair enough explanation. The angry response is a bit over the top.

The production ramp up has been extraordinarily fast, particularly for a product that requires specialist storage and handling at the plant, through filling and into distribution.
Not really. The biggest factor in unanticipated increase in demands on Pfizer most likely the shambolic Oxford vaccine development program. If they had hit their anticipated approval timelines that would take a lot of pressure off Pfizer. Moderna struggling to ramp up their manufacturing isn’t helping.

Coronavirus: EU anger over delayed Pfizer vaccine deliveries
Less than ideal.
I could be wrong but I think that nasal vaccines reduce transmission in some way.
Possibly something like this

Thanks for the interesting information. As far as I know, there is very little evidence regarding the stimulation of IgA production by nasal spray vaccines (not only against SARS-CoV-2). Even if they do, IgA only provides a transient protection as it is known for its short half life. The only way a vaccine can provide a long term protection is to trigger immune responses in blood and let the memory immune cells recognize the antigen.Nope. Nasal sprays stimulate IgAs in a way that parenteral vaccines don’t. Because IgAs are in located in mucus membranes (e.g. the lining of your nose).
They do get into your blood and cause a more generalised immune response (IgG, IgM, T cells etc) but it’s the route they take to get there that can cause a different, more effective, response if you’re vaccinating against a disease that enters your body the same way.

What happened with the Oxford approval program?

They ran their studies in a fairly chaotic way. With significant differences in dosing regime and patient population in sites in different countries. Which causes a headache when it comes to combining all the data for regulatory approval. It’s why they’re taking much longer than the Pfizer/Moderna vaccines to go through that process.

Grandparents both had their second Pfizer vaccine last Sunday. The family has had a collective sigh of relief, particularly as my Grandma has quite bad asthma (and both are in their mid 80's).
Is it around 1-2 weeks after the second vaccination that it takes full effect? They're desperate to get out of the house (even to go to a supermarket) at this point.
That is great news. I seem to remember 7 days after the second shot maximum immunity was recorded. But don't take my word/memory as gospel.
That's great news, can totally understand that you're all quite relieved! My grandparents are 90 and 88 but are only scheduled to get their first one somewhere around March (and probably later, given our government's failures). Especially frustrating since we can't get my granddad to stay inside the houseGrandparents both had their second Pfizer vaccine last Sunday.

Just me a bit fed up of these stories? I don't think the media have been that doomongering as claimed during the pandemic but I find this constant stream of this % not wanting to apparently take the vaccine from a random pool a bit frustrating when we're seeing daily coverage now of over 80s pretty much queueing round the block to get their jab which is brilliant and I commend them.
Pretty happy we're already at 5% of whole population and take has been very high in a fair few regions so hopefully we'll get to the 15m point sometime in February and slowly unlock from there every month.
Overall, the study found high levels of willingness to be vaccinated, with 82% of people saying they were likely or very likely to have the jab – rising to 96% among people over the age of 75.
Over 70’s and those identified as Clinically Extremely Vulnerable to begin receiving letters from tomorrow.

We all have seen plenty of news about the side effects of the vaccines. Actually, what is the rate of adverse effects, and is it significantly higher than that of routine vaccines?
Didn't I read that half of over 80s were vaccinated? and they are moving to over 70s ? What about the other half? Not keen on getting a vaccine?
The maintenance guy at another of my companies nursing homes just tested positive on a rapid test 3 weeks after his first Pfizer jab. Hopefully it's a false positive, otherwise its a little worrying.

That's what I'm thinking. Local media here keep exaggerating these rare events and make the vaccines sound unsafe. Pretty sure many would take that story and refuse to get vaccinated.Very low. I think the US has only had 21 significant allergic events (from memory) from 2 million vaccinations. 71% occurred during the 15 min supervision period and all recovered fine.
Hmm. India have vaccinated 200k and reported 447 adverse reactions.Very low. I think the US has only had 21 significant allergic events (from memory) from 2 million vaccinations. 71% occurred during the 15 min supervision period and all recovered fine.
Just to update this for those interested, his full test did indeed come back positive. So for him, the first jab didn't prevent him getting it. The home he works at has a bad outbreak so whether that played a part I don't know. If the first jab only protects you 50% as first stated its not too surprising.
Re side effects. We had our whole home vaccinated with the Oxford including staff for those who hadn't had the Pfizer jab. Quite a lot of people getting side effects, a day or 2 of fluey symptoms. However, I would not be too surprised if a lot of it is a bit of mass hysteria. I had the second Pfizer jab last Monday and had no reaction, maybe a little drowsy but fine.

Getting the Oxford one and another one which is still in phase 3 trial.. but they might be classifying it differently.

So couple of rumours I've picked up this weekend. Johnson and Johnsons single shot vaccine is 100% effective and there is a study of US students to be published who caught covid, regardless of symptoms, 60% developed heart issues. See if these come true in the coming weeks.
