Vaccines work. They have saved lives and reduced the burden of illness and disability. We know this due to several things. One is how Obama has harmed vaccination programs. Another is the eradication of Smallpox.
Obama did many things as US president, Like Trump, some of this was good and some of it was not so. When the USA assassinated Osama bin Laden in Operation Neptune Spear, they obtained information on this presence through a hepatitis vaccination programme allowing them to obtain DNA evidence of his presence. Militants in Afghanistan and Pakistan started to attack healthcare workers who had been trying to eradicate polio and one of the reasons for this was the perception that healthcare workers were continuing to aid the USA. Vaccination rates dropped and the rates of polio increased. But when vaccination rates increased, the cases of polio fell. Likewise, falling vaccination rates due to increasing unrest have resulted in more cases of polio in both Afghanistan and Pakistan. To be fair to Obama, he cannot be blamed for all of this as extremists there have been spreading lies and fake news about vaccinations.
My next example of how vaccinations work is smallpox. Put simply, it is not seen anymore. And that is thanks to vaccination. Those who are against vaccination claim that there are other reasons for the end of smallpox, this including hygiene measures. But while other diseases have continued in areas of poor hygiene, smallpox has been eradicated.
At present in the world, many are hoping that a vaccination to COVID-19 will be developed. An effective and safe vaccine may not be possible though. Even trials into this have been subject to fake news with reports being shared that the main volunteer into this has died. If Dr Elisa Granato has, she has been able to speak from beyond the grave to state that she is alive!
