The evidence so as to explain a new mother that measles vaccine (MMR vaccine) is safe and effective. Introduction: Measles is a contagious disease that spreads through air and is caused by paramyxo virus. It starts with fever and tiny red spots like rashes on skin. The most affected are children who are less than one year old. It can be prevented by measles vaccine known as MMR vaccine. It protects against three disease conditions- measles, mumps, and rubella.

Question

Suppose you are designing a study to determine whether a vaccine is effective. You recruit volunteers and then assign them into two groups. Which of the following is a better way to determine if the vaccine works in a wide variety of people? (a) Recruit people from a variety of backgrounds: different ethnicities, ages, sexes, etc... and then randomly form two groups. (b) Recruit people for the study who are very similar to one another, such as married nonsmoker female nurses in their forties who don't drink with no health problems and good incomes, then randomly form two groups

Polio (poliomyelitis) is a serious disease that either kills or paralyzes a large number of people (especially children) before the development of the vaccine. The first vaccine against polio was developed by the American doctor Dr. Salk in the 1950s. The effectiveness of the vaccine was studied using the following experimental setup: 400,000 elementary school children from grades 1, 2, and 3 participated in the experiment. 200,000 children were vaccinated and 200,000 children were not vaccinated. For each child in the experiment, a coin was flipped. If the result of the flip was heads, the child was placed in the treatment group and received the vaccine injection. If the result was tails, the child was placed in the control group and received a placebo injection (dummy vaccine). The health status of the children was then monitored over a certain period. The children participating in the experiment, their parents, the doctors who administered the injections, and the doctors who…

This is a hypothetical scenario. A recently emerged virus has been transmitting and mutating rapidly in humans throughout the world. If a vaccine that stops transmission of all current circulating variants of the virus in humans is utilized and herd immunity is achieved throughout the world, would this essentially stop 1) further transmission of the virus; 2) further mutation of the virus, respectively? Why/why not? Please answer the question succinctly and in bullet points!
