Center for Infectious Disease Control and Control (CDC) inapereka chidule cha sayansi ponena za kuchuluka kwa chitetezo cha mthupi chifukwa cha matenda poyerekeza ndi chitetezo choperekedwa ndi katemera.

Chitetezo chotsatira matenda kapena katemera chimakhala chogwira mtima, makamaka m'miyezi 9-6 yoyambirira, koma sichitha kuti mutha kutenga matenda.

Chitetezo pambuyo pa matenda: Pafupifupi 90% mwa omwe adachira.

1- Zaka: Pambuyo pa zaka 60, mphamvu ya chitetezo cha mthupi imachepa

2- Kuopsa kwa matendawa: matendawo akamakula kwambiri, ndiye kuti chitetezo chake chimakhala bwino (kutanthauza kuti wodwala yemwe ali ndi chisamaliro chachikulu amakhala ndi chitetezo chokwanira ngati atakhala ndi moyo")

3- Matenda ophatikizana: Matenda osatha monga matenda a shuga, kuthamanga kwa magazi, kulephera kwa impso ndi chiwindi zonse zimafooketsa chitetezo chamthupi chotsalira.

Chitetezo pambuyo pa katemera: pakati pa 80 ndi 93%, kuchuluka kwa chitetezo chokwanira, chomwe chimakhala miyezi 9-6

Pambuyo pa mlingo womaliza wa katemera wa Pfizer ndi Moderna, chitetezo chamthupi chimafika 90%.

Mlingo umodzi wa katemera wa Johnson & Johnson 66%

Mlingo wowonjezera wa Johnson & Johnson 94%

Ma antibodies amasiyana pakati pa katemera ndi matenda

Ngakhale katemera amapereka ma antibodies apamwamba komanso enieni, koma nthawi zambiri amalimbana ndi puloteni imodzi monga mapuloteni a spike.

Matendawa amayambitsa chitetezo chokwanira chokhala ndi ma antibodies a zabwino zingapo..

Choncho, kuphatikiza njira ziwiri za katemera wotchedwa hybrid immunity kumapereka zabwino zomwe tingapereke kwa njira zonse ziwiri za chitetezo.
