Popular Post TooMuchTime Posted September 5, 2021 Popular Post Share Posted September 5, 2021 3 minutes ago, tonray said: Actually the initial "Boosters" are given at a much more frequent schedule: The World Health Organization (WHO) recommends six doses in childhood starting at six weeks of age.[2] Four doses of DTaP are to be given in early childhood.[14] The first dose should be around two months of age, the second at four months, the third at six, and the fourth from fifteen to eighteen months of age. There is a recommended fifth dose to be administered to four- to six-year-olds.[14] Td and Tdap are for older children, adolescents, and adults and can be injected into the deltoid muscle.[14] These are boosters and are recommended every ten years. It is safe to have shorter intervals between a single dose of Tdap and a dose of the Td booster.[21] If you read the text it says boosters are recommended every ten years. The initial shots in the beginning are not considered boosters, just like how the 2 pfizer shots are not boosters. 2 1 2 Link to comment Share on other sites More sharing options...

smedly Posted September 5, 2021 Share Posted September 5, 2021 47 minutes ago, tonray said: They are not really mixing two vaccines. Each vaccine independently promotes a seperate immune system response and prepares your body to defend against Covid-19 should you become infected. By the time the second dose is adminstered, not only has the first vaccine and all traces of it long disappeared from your system, the immune response has also waned, which of course is the reason for the second shot requirement. Think of childhood vaccinations, kids are jabbed with 10 or more recommended vaccines between 1 year and 18 years old, they are not mixing different vaccines....think of each one as an independent dose. another expert 2 Link to comment Share on other sites More sharing options...
Bkk Brian Posted September 5, 2021 Share Posted September 5, 2021 1 hour ago, Henryford said: Can anyone reference for me the scientific papers where they have tested the effect of mixing different vaccines? There is some international study evidence. A mix-and-match approach to Covid vaccines - using different brands for first and second doses - appears to give good protection against the pandemic virus, a UK study has found. The Com-Cov trial looked at the efficacy of either two doses of Pfizer, two of AstraZeneca, or one of them followed by the other. Although the UK said: "The UK's deputy chief medical officer, Prof Jonathan Van-Tam, said there was no reason to change the current successful same dose vaccine schedules in the UK, however, given vaccines were in good supply and saving lives." https://www.bbc.com/news/health-57636356 There is also another study that says one dose AZ and one dose Pfizer gives better protection from vaccine waning. 2 Link to comment Share on other sites More sharing options...

DrJack54 Posted September 5, 2021 Share Posted September 5, 2021 (edited) No doubt been asked in other threads...... Many of us have had first shot of AZ and due for second jab October or whenever. Would be nice to know which vaccine to expect. Another AZ or Pfizer. Edited September 5, 2021 by DrJack54 1 Link to comment Share on other sites More sharing options...

Their only option in winter of 2020 was to get AZ from India. The approach was to get as many vaccinations into as many people as possible for first dose. And wait as long as possible for the second jab While they were doing that other orders were in for Pfizer, Moderna etc. So second jab time comes around and options were available. The problem for a lot of folks is that most countries don't recognize mixing and matching for entry. 1 Link to comment Share on other sites More sharing options...

Chongalulu Posted September 5, 2021 Share Posted September 5, 2021 1 hour ago, Neeranam said: What is the difference? Do Thai computers not have Google? It would have been quicker to Google than write your question ???? Both mRNA and viral vector vaccines contain instructions that teach our cells how to create "spike proteins", which is the protein found on the surface of the virus that causes COVID-19. Once your cells produces COVID-19 spike proteins, your immune system recognizes that those proteins don’t belong in your body and creates antibodies to stop the virus from spreading and causing damage when you are exposed to it. Neither vaccine contains the virus that causes COVID-19. The instructions in the mRNA vaccines are messenger RNA (mRNA), the genetic material that tells your cells how to make proteins. The mRNA is surrounded by tiny lipids (fatty molecules) which help mRNA enter directly into your cells. Once your cells create the spike proteins, your body breaks down the mRNA. In viral vector vaccines, spike protein DNA is placed inside a modified version of a different virus that doesn’t cause illness. This non-harmful virus delivers the DNA instructions to your cells – this virus is called the vector. 2 Link to comment Share on other sites More sharing options...

This is the only reason why they are mixing - to remove this as they do not want to cancel it as it is tied in with an order of very excellent self stuffing brown envelopes manufactured in China.

Popular Post bob2 Posted September 5, 2021 Popular Post Share Posted September 5, 2021 Henryford, The Com-Cov study, which looked at giving the doses four weeks apart in 850 volunteers aged 50 and above, found: AZ followed by Pfizer induced higher antibodies and T cell responses than Pfizer followed by AZ Both of these mixes induced higher antibodies than two doses of AZ The highest antibody response was seen after two doses of Pfizer, and the highest T cell response from AZ followed by Pfizer 2 1 Link to comment Share on other sites More sharing options...

It's ok, you're probably safe, we googled it. We have a bucket load of Sinovac we need to use and need to make our numbers look better on paper. Instead of mixing the vaccines, why not have Buy one get one free. But the Sinovac must all be free for those who want it but don't care if it really doesn't work.

Popular Post vinci Posted September 5, 2021 Popular Post Share Posted September 5, 2021 i don't know what's all the fuzz about vaccine, either you take it or you don't the fact is this virus will not going away anytime soon probably will last for another 2-3 years, by this rate it's spreading like wild fire it is more now then when it started a year back for every country and that's including the United Stated, vaccine only last you up to a year and it will decline, eventually everybody will need to retake the vaccine, hopefully we all get better vaccine by then there's even talk about making vaccine into a pills form instead of shot, the best solution is isolate yourself as much as possible and hunker down for the next 2 year, do what is necessary for daily living avoid crows and protect yourself from other 2 2 Link to comment Share on other sites More sharing options...

Vaccines don't stay in the system long enough for there to be interactions (unless you injected them at the same time). The main risk with combining different vaccines is that each vaccine carries different side effects and risks. Where these risks have independent risk factors, you're essentially doubling your risk of side effects. It's a trivial increase but it's worth considering given that the medical benefits of mixing vaccines are limited. 3 1 1 Link to comment Share on other sites More sharing options...

StevieAus Posted September 5, 2021 Share Posted September 5, 2021 3 hours ago, Trujillo said: I know a man who has had 4 shots of variously available vaccines here in Chiang Mai. I'm not sure if this is sound reasoning but then, perhaps he's taken the "common sense" message about adding masks for added protection. More is better. Is this a common practice in other countries (Western countries)? I have no idea. I'm not at all sure about mixing medicines/doses. I'm trying to think of other situations and medicines that we do this with. Do we do this with seasonal influenza? I don't know; I've never had a flu shot (and incidentally, have not had the flu for at least two decades). This is just my opinion and I have no links to offer pro or con. By the way, I'm not sure this fellow I mention is finished loading up on vaccine injections. Now with this buzz about boosters, I will have to ask him and report back. Each year the experts decide which four strains are to be included in the flu vaccine. Doctors often mix drugs such as antibiotics nothing new there. 1 Link to comment Share on other sites More sharing options...
