Introduction:
Pertussis is also known as whooping cough is a respiratory illness in which the person has bouts of cough. It is a contagious disease and is caused by the bacteria Bordetella pertussis.

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…
Yearly vaccination is the primary means of preventing and controlling flu outbreaks. Here 'yearly' is important because:
New vaccines with better efficacy are produced each year
Circulating strains of influenza viruses change from year to year
New vaccines with up-to-date strain components are produced each year
Who is at higher risk of developing severe pneumonia when infected with SARS-CoV-2?
An undergraduate
A student at high-school
A 6-month-old baby
A 70 years old man with diabetes and high blood pressure
Which of the following statements
about vaccines is NOT correct?
Smallpox vaccinations are no longer
given in the United States.
The MMR vaccine should be given to
children before they enter
kindergarten.
There is no proven link between the
MMR vaccine and autism.
One of the earliest vaccines protected
people against smallpox.

- There are two tests for a disease, one is rapid and the other is slow. Given that an individual is infected, the rapid test will register positive 40% of the time, while the slow test will register positive 80% of the time; additionally, both tests will be positive 35% of the time. Suppose in the above example that people not infected always test negative for both tests. Suppose in the above example that people not infected always test negative for both tests. 5. Of the people in the population who are tested, 75% of their results from the slow test are positive. What is the chance that a persons has the virus conditioned on getting negative result on the slow test?arrow_forwardA malaria vaccine has proved to be 77% effective in early trials and could be a major breakthrough against the disease, says the University of Oxford team behind it. Malaria kills more than 400,000 people a year, mostly children in sub-Saharan Africa. But despite many vaccines being trialled over the years, this is the first to meet the required target. The researchers say this vaccine could have a major public health impact. When trialled in 450 children in Burkina Faso, the vaccine was found to be safe, and showed "high-level efficacy" over 12 months of follow-up. Larger trials in nearly 5,000 children between the ages of five months and three years will now be carried out across four African countries to confirm the findings. Malaria is a life-threatening disease caused by parasites that are transmitted to people through mosquito bites.

- Many hospitals are making seasonal flu shots mandatory for their employees.
