Vaccine uptake in the UK decreased from 81% to 31%, and pertussis epidemics followed, leading to the deaths of some children. The mainstream medical opinion continued to support the effectiveness and safety of the vaccine; public confidence was restored after the publication of a national reassessment of vaccine efficacy.
An oral polio vaccine turned out to be effective when vaccinations were administered by volunteer staff without formal training; the results also demonstrated increased ease and efficiency of administering the vaccines. Effective oral vaccines have many advantages; for example, there is no risk of blood contamination.
However, the effectiveness of passive immunization in comparison to active measles vaccine is not clear. [76] The MMR vaccine is 95% effective for preventing measles after one dose if the vaccine is given to a child who is 12 months or older; if a second dose of the MMR vaccine is given, it will provide immunity in 99% of children.

[158] The hepatitis B vaccine prevents infection with hepatitis B virus and thus decreases the risk of liver cancer. [158]

Additionally, an analysis of changes in mortality post Medicaid expansion suggests that Medicaid saves lives at a relatively more cost effective rate of a societal cost of $327,000 to $867,000 (equivalent to $415,143 to $1.1 million in 2023 [31]) per life saved compared to other public policies which cost an average of $7.6 million (equivalent ...
