Do you think politics can save lives??

If you think "yes" is the answer, the opposite is also true.　#ph260720 #HPVV #JAPAN　

#HPV is a common virus that infects the reproductive tract and can cause #cancers in males and females. This would have a serious impact on our lives. #ph260720 #HPVV #JAPAN

In 2013, the #Japanese government issued a statement stopping the active recommendation of #HPVV and implemented a policy of not including it in the routine vaccination. #ph260720 #HPVV #JAPAN

Do you imagine the impact???

Surprising fact from @minpapiHPV. This bar graph shows the #HPVV vaccination rates in developed countries, and the bottom graph, which is only as big as the frame line, is Japan. The policies made most "samurai" choose to take off their armor. #ph260720 #みんパピ

However, if this armor of #HPVV is useless or harmful, this choice is not a mistake. #ph260720

First, let's talk about effectiveness.
The risk of Invasive Cervical Cancer has been found to be reduced by 88% when #HPVV is administered at age 17 or younger, and by 53% when #HPVV is administered at ages 17-30. #ph260720

Second, safety.
#HPVV has been vaccinated hundreds of millions of times worldwide, and its safety has been proven. Even if severe side effects occur, 90% recover and the risk of developing cervical cancer is much higher than that of having severe symptoms after #HPVV #ph260720

Now, what do you think happened in Japan that resulted in the refraining from using this effective and safe vaccine? #HPVV #ph260720

It is estimated that the number of cervical cancer cases has increased by about 4,500 per year due to the sharp decline in vaccination rates after stopping the active recommendation of #HPVV. #ph260720

Certainly, it is not entirely due to this policy. However, in response to the first tweet, I guess we could say that policies can sometimes put people's lives in danger. #ph260720 #HPVV

According to the paper presented by @IPVSociety and @placentadoc, HPV infection may be associated with preterm birth. #ph260720 #HPVV

In conclusion, I believe that evaluating the effect of #HPVV only by death may underestimate the effect of #HPVV, and other axes such as preterm birth should also be evaluated. #ph260720

Anti-vaxxers are also a major problem in the current COVID-19 pandemic. In general, what do you think is the cause of vaccine avoidance? #ph260720 #HPVV
