Answer:
Explanation:
Evidence suggests that receipt of BCG and MCV reduce overall mortality by more than would be expected through their effects on the diseases they prevent, and receipt of DTP may be associated with an increase in all cause mortality. Although efforts should be made to ensure that all children are immunised on schedule with BCG, DTP, and MCV, randomised trials are needed to compare the effects of different sequences.
Answer:
The MMR vaccine is a vaccine against measles, mumps, and rubella (German measles). The first dose is generally given to children around 9 to 15 months of age, with a second dose at 15 months to 6 years of age, with at least 4 weeks between the doses. After two doses, 97% of people are protected against measles, 88% against mumps, and at least 97% against rubella. The vaccine is also recommended in those who do not have evidence of immunity, those with well-controlled HIV/AIDS,and within 72 hours of exposure to measles among those who are incompletely immunized. It is given by injection.
The MMR vaccine is widely used around the world, with over 500 million doses having been given in over 100 countries as of 2001. Measles resulted in 2.6 million deaths per year before immunization became common.This has decreased to 122,000 deaths per year as of 2012, mostly in low-income countries. Through vaccination, as of 2018, rates of measles in North and South America are very low. Rates of disease have been seen to increase in populations which go unvaccinated.Between 2000 and 2016, vaccination decreased measles deaths by a further 84%.
Side effects of immunization are generally mild and go away without any specific treatment. These may include fever, and pain or redness at the injection site. Severe allergic reactions occur in about one in a million people. Because it contains live viruses, the MMR vaccine is not recommended during pregnancy, but may be given while breastfeeding.The vaccine is safe to give at the same time as other vaccines.[11] Being recently immunized does not increase the risk of passing measles, mumps, or rubella on to others.Vaccination does not increase the risk of autism.The MMR vaccine is a mixture of live weakened viruses of the three diseases.
