Online Class Notes (Jesse)

the title is why you cant compare covid 19 vaccines. Vaccines have different efficacy rates – it’s natural to compare vaccines just by efficacy rates but I think that’s wrong. If you really know how vaccines work, and what is efficacy rate then you will find that’s wrong. The number is not even the most important number to find which one is the most effective. So, the first thing I learned from the video is what is efficacy rate. So, a vaccines efficacy rate is calculate through a large clinical trial. The participates in every trial will be divided / separated to 2 groups. One group will take the real vaccines, one group will take the placebo. Then the participates will live their lives and scientists will try to track them, if they will get infected in a few months, and the percentage of the infected participates from the vaccine group determines the efficacy rate of that vaccine. But, the question is: those clinical trials took place in very different period of time, and very different circumstances so the number only means just what happened in the trial not in the future. So, according to that video, there are 3 vaccines which produced separately by pfizer, ……. the rate of J&J is lower than the other 2 but actually the J&J trial took place in wider / larger places / regions including the US, brazil and South Africa, and the other one only took place in the US. So, that means you can’t just compare them one apple to apple. In addition I think the goal of the vaccine of COVID 19 is not just protecting any infections at all. Actually it’s just, what we care most is that if someone got infection by COVID 19 whether he or she will have serious symptoms or have to be hospitalized if he got vaccine. Actually, all the 3 vaccines are effective enough in protecting people from death or serious symptoms. So to sum up the video just told me a result or knowledge which is don’t compare vaccines just by efficacy rates …. opportunity to take vaccine just take it. The best one right now is the one you are offered.

the title is why you cant compare covid 19 vaccines. Vaccines have different efficacy rates – it’s natural to compare vaccines just by considering / using their efficacy rates but I think that’s wrong. If you really know how vaccines work, and what the efficacy rate is then you will find that’s wrong. The number is not even the most important number to judge / determine / work out / decide / measure which one is the most effective. So, the first thing I learned from the video is what the efficacy rate is. So, a vaccines efficacy rate is calculated through a large clinical trial. The participants in every trial will be divided / separated into 2 groups with one group taking the real vaccines, and the other group taking placebos. Then the participates will live their lives and scientists will try to track them to see whether they will get infected within a few months, and the percentage of the infected participants from the vaccine group determines the efficacy rate of that vaccine. But, the issue / problem / fact is: those clinical trials took place in very different periods of time, and very different circumstances so the number only means just what happened in the trial not necessarily what will happen in the future. So, according to that video, there are 3 vaccines which were produced separately by pfizer, ……. with the J&J vaccine having a lower rate than (that of the other 2) the other 2 but actually the J&J trial took place in a wider range of places / in a greater number of places / in a larger variety of places including the US, brazil and South Africa, and the others(with the others) only took place in the US. So, that means you can’t just compare them directly / “apples to apples”. In addition I think the goal of the vaccine of COVID 19 is not just protecting from any infections at all. Actually it’s just, what we care about most is that if someone gets infected by COVID 19 whether he or she will have serious symptoms or have to be hospitalized if they got vaccinated. Actually, all the 3 vaccines are effective enough in protecting people from death or serious symptoms. So to sum up the video was trying to teach us not to compare vaccines just by their efficacy rates… and right now if you have an opportunity to take a vaccine, just take it. The best one right now is the one you are offered.
