Mushure mekuongorora mishumo yevanopfuura 45,000 vatori vechikamu vekiriniki yekuedzwa, Harvard Medical School vaongorori vakati kuwanda kwe Mushonga unobetsera kudzivirira covid-19 'maside effects' ayo vanhu vanoti vanosangana nawo mushure mejab, zvichikonzerwa nezvinotarisirwa nevanhu kwete nemishonga.
Vanhu vakawanda vari kunetsekana nazvo Mushonga unobetsera kudzivirira covid-19 'maside effects' vanovanzwa kunyangwe vakawana placebo, tsvagiridzo itsva inoratidza.
Yakasiyana-siyana 'systemic' mhedzisiro, sekutemwa nemusoro, kuneta, uye kurwadziwa kwemajoini zvakashumwa mumahafu ese eboka rekutsvagisa: nevaya vakagamuchira akasiyana eCCIDID-19 ekudzivirira, uye neavo vakagamuchira placebo nekusaziva.
Mushure mekuongorora mishumo, masayendisiti kubva kuBoston-based Beth Israel Deaconess Medical Center akasvika pamhedziso yekuti iyo inodaidzwa kuti 'nocebo effect' - manzwiro asingafadzi anokonzerwa nekufunganya kana tarisiro yakaipa - yakaverengera zvikamu zvitatu muzvina zvezvose zvakashumwa zvinokonzerwa nemishonga.
Chirevo, icho chakabudiswa mumagazini yeJAMA Network Open, inoti 35% yevakagamuchira placebo vakashuma migumisiro mushure mekutanga dosi uye 32% mushure mechipiri. Zvakanyanya kukosha "zviitiko zvakashata" (AEs) zvakataurwa mumapoka ekudzivirira, asi anonzi "nocebo mhinduro" akaverengera "76% ye systemic AEs mushure mekutanga. Mushonga unobetsera kudzivirira covid-19 dose uye 52% mushure mepiritsi yechipiri.
Masayendisiti anocherekedza kuti, kunyangwe zvikonzero zvekuzeza kwekudzivirira "zvakasiyana uye zvakaoma," kunetseka pamusoro pezvinogona kuitika kubva Mishonga inobetsera kudzivirira covid-19 "zvinoita senge chinhu chikuru" uye "zvirongwa zvekudzivirira veruzhinji zvinofanirwa kufunga nezvemhinduro idzi dzakakwirira dzenocebo."
Mumwe Harvard Medical School mapurofesa ane chekuita nekutsvagisa, akatsanangura sainzi kuseri kwe "nocebo mhedzisiro," achiratidza kuti "zvisina kujeka zviratidzo," semusoro uye kuneta, zvakanyorwa mumabhuku akawanda eruzivo seyakajairika mhedzisiro yeCCIDID-19 vaccine.
"Uchapupu hunoratidza kuti ruzivo rwerudzi urwu runogona kuita kuti vanhu vataure zvisiri izvo zvinowanzoitika zuva nezuva manzwiro anobva mujekiseni kana kukonzera kushushikana uye kunetseka kunoita kuti vanhu vangwarire manzwiro emuviri nezvezviitiko zvakaipa," akadaro.
