We have a vaccine that prevents shingles. We have a vaccine that markedly lowers the risk of dementia. We have a vaccine that might even slow aging itself.

Conveniently, these three vaccines are actually just one: the shingles vaccine.

In 2006, the FDA approved the vaccine Zostavax for adults aged 60 and older. For people previously infected with varicella-zoster virus, which causes chickenpox, the infection actually doesn’t end. The sneaky virus lies dormant in nerve tissue and can subsequently spring to life to cause shingles. Zostavax, and its more effective replacement, Shingrix, train your immune system to fight varicella-zoster in case it emerges from hiding to attempt a bodily coup.  

That’s a good thing because you really, really don’t want shingles. About 1 in 3 Americans will get it at some point. Its signature symptoms are a bubbly, blistering rash that traces the infected nerve, coupled with debilitating pain that’s been the subject of many painful-to-read Reddit posts. Sufferers use words and phrases such as “unrelenting,” “white hot,” and “I wish I could rip my arm out!”

So if you’ve had chickenpox in the past, it’s definitely worth your while to get vaccinated. The CDC actually recommends the shot for all adults aged 50 and older and all adults aged 19 and older who have weakened immune systems – because oftentimes you can be infected with varicella-zoster virus even if you’ve never developed chickenpox.

O God, by whose providence the blood of the martyrs is the seed of the Church: Grant that we who remember before thee the blessed martyrs of Uganda, may, like them, be steadfast in our faith in Jesus Christ, to whom they gave obedience even unto death, and by their sacrifice brought forth a plentiful harvest; through Jesus Christ our Lord, who liveth and reigneth with thee and the Holy Spirit, one God, for ever and ever.

3 June 1886, 32 young men, pages in the court of Bugandan King, burned to death at #Namugongo. As Christians, they refused king’s homosexual advances & demand to renounce faith. Led to many coming to faith: the blood of the martyrs is the seed of the church. #Uganda #martyrsday pic.twitter.com/K8ljxhlATB

Lord God Almighty, who hast given to us the vision of thy holiness, and therewith of our unworthiness to be thy witnesses: Touch, we pray thee, our lips with thy cleansing fire; that so cleansed and hallowed, we may go forth amongst men as those whom thou hast sent; for Jesus Christ’s sake.

—Daily Prayer, Eric Milner-White and G. W. Briggs, eds. (London: Penguin Books 1959 edition of the 1941 original)

But when Cephas came to Antioch I opposed him to his face, because he stood condemned. For before certain men came from James, he ate with the Gentiles; but when they came he drew back and separated himself, fearing the circumcision party. And with him the rest of the Jews acted insincerely, so that even Barnabas was carried away by their insincerity. But when I saw that they were not straightforward about the truth of the gospel, I said to Cephas before them all, “If you, though a Jew, live like a Gentile and not like a Jew, how can you compel the Gentiles to live like Jews?” We ourselves, who are Jews by birth and not Gentile sinners, yet who know that a man is not justified[a] by works of the law but through faith in Jesus Christ, even we have believed in Christ Jesus, in order to be justified by faith in Christ, and not by works of the law, because by works of the law shall no one be justified. But if, in our endeavor to be justified in Christ, we ourselves were found to be sinners, is Christ then an agent of sin? Certainly not! But if I build up again those things which I tore down, then I prove myself a transgressor. For I through the law died to the law, that I might live to God. I have been crucified with Christ; it is no longer I who live, but Christ who lives in me; and the life I now live in the flesh I live by faith in the Son of God, who loved me and gave himself for me. I do not nullify the grace of God; for if justification were through the law, then Christ died to no purpose.

–Galatians 2:11-21
