Me ya sa?
Muhimmiyar rawar da hukumomin kiwon lafiyar jama'a ke takawa a lokacin bala'in cutar ita ce gudanar da nazarin cutar sankarau don sanin adadin mutane nawa ne suka samar da ƙwayoyin rigakafin cutar daga kamuwa da cutar.

Spain ta yi irin wannan babban, bazuwar binciken tun da wuri yayin bala'in yayin da Sweden ta yi jerin ƙananan binciken bazuwar lokaci-lokaci.
A cikin Amurka, wannan muhimmin aiki an bar shi ga ɗaiɗaikun masana kimiyya, amma kawai suna da albarkatun don gudanar da ƙananan bincike a cikin iyakataccen yanki kamar. Santa Clara County Nazarin. A yanzu CDC ta sami aikinta tare da binciken ƙasa. Sakamakon yana haskakawa.
A cikin Afrilu 2020, binciken Santa Clara ya nuna cewa kashi 3% na yawan jama'arta sun kamu da cutar.

Menene ma'anar wannan? Mun san cewa rigakafi na halitta bayan murmurewa na covid yana samarwa kyakkyawan kariya a kan kamuwa da cututtuka na gaba, kuma yayin da covid zai kasance tare da mu har tsawon rayuwarmu, zai zama wani abu da tsarin garkuwar jikin mu zai iya jurewa ta yadda yake tafiyar da sauran ƙwayoyin cuta guda huɗu da ke yaduwa.

Don gyara wannan, kwanan nan Nazarin Danish yayi amfani da RCTs don kimanta yawan mace-mace.

Wannan ya bambanta da allurar rigakafin adenovirus-vector (AstraZeneca da Johnson & Johnson), tare da mutuwar 37 a cikin allurar (95% CI: 19-70).
Ga yara, ba ma da wannan. The gwajin rigakafin cutar bazuwar sun nuna cewa za su iya hana ƙananan cututtuka a cikin yara ba tare da kamuwa da cutar ta covid ba, amma daga binciken binciken mun san cewa wannan kariyar raguwa da sauri.
