Very old vaccines used to use "inactivated" copies of a virus, or similar but less dangerous viruses (cowpox, for smallpox), but the modern ones just contain some molecules that mimic parts of the virus to train your immune system.
Truly? I didn’t know that. Thanks for letting me know :)!
True that. Do you remember how one of the vaccines must be kept frozen? That is because it contains small parts of viral RNA (genetic intermediate that serves as a guideline for body to create proteins), which is rather unstable at room temperature and is automatically destroyed by enzymes (after few hours). So with that vaccine, your body's immunity "teacher" cells start producing one of viral proteins for a short period of time (normally these cells would present pieces of germs eaten by your immunity), which trains a whole generation of immunity cells specialised against virus that causes covid-19.
@Kuba-kun Oh, cool! I hadn't looked into it in that much detail. Those would be the T-Cells, I guess?I know the Oxford/AstraZenica vaccine doesn't need to be kept so very cold, fridge or freezer levels, so it'll be a lifesaver in larger or less wealthy countries.
Yeah, that should be it, Antigen presenting cells and T cells (tho I am only a microbiologist-bacteria, not immunologist).And those of Oxford should contain fragments of (more stable) DNA.*Had to look into it since facebook in my country is full of antivaxers fearing "frozen stuff".

Not true, there is no evidence yet that it won't.
Yeah, yeah it kinda does. Do you even know how vaccines are created? The vaccine is a weaker version of the virus or bacteria that gets introduced into the ghost body so they they can create antibodies. The new mutated strain has changed the genetic structure. That is why when people get the flu shot and still catch the flu. The excuse is that you were vaccinated for strain A and you caught strain B. The last time I got vaccinated for the flu the CDC said is was only 35% effective. I have gotten sick in the last 7 or 8 years. Not even do much as the sniffles. I only get vaccinated so I don't have to listen to my doctor go on every visit as to why I should get vaccinated. I just get it so I can get through the visit without the lecture.
Yes, I do know, I've been watching a YouTube channel by a retired teaching nurse called Dr John Campbell, he seems to know his stuff. I've been having the flu jab for the last 5 years except I missed out on it last year. I went to concert mid November last year and stood in a crowd of people waiting to get in to the venue. The following week I was due to fly out to Spain for a holiday and the day before I woke up to a cough and felt feverish. On the next morning I felt fine and flew out to southern Spain but by the time I got to the hotel the fever returned and I was having trouble breathing and a pain had developed down my right ribcage. I spent the next 3 days in the hotel room not eating, just drinking water. Just the act of walking from the bed to the bathroom left me breathless. By the third day I was able to go outside and walk but still slightly breathless. I have never felt that ill in my life before, it was quite scary so if this virus feels anything like what I had I will gladly take the vaccine.
Also, you don't get "infected with COVID-19". COVID-19 is the disease you may or may not develop after being infected with the virus SARS-CoV-2. This is basic knowledge everyone should know by now.
Well that's not true, young people have died from it.
@Dayman343 yup. just like they die to the regular flu. that's old news. but the likelyhood is way too low to make a vaccination worth while. specially in case of a highly experimental, hastily botched one.
It seems to work so I'll take it
@Dayman343 yeah it reduces your chances to have a positive test result by 90% that is from 0,4% to 0,04% xD the risk is already super low, if you're not 70. how many flu shots have you taken in your past if i may ask? flu has quite litterally the same chance of killing you.
I had my 4th one around 2 weeks ago
i bet you wear your bicycle helmet and a condom when you go to bed alone xD just to be extra safe.
@Dayman343 but i must say i confused you with the original asker of the question, i thought you're like 20. it says on your profile, you're 64, at which age, taking those vaccines becomes a bit more reasonable :D
