"Herd Immunity" tih thumal hi i hre tawh ngei ang. Hemi chungchang hi sawi a tam hle a, a bik takin COVID-19 hripui leng lai hian. Chuti a nih chuan, eng nge a awmzia tak? Vawiin hian tlem han sawi ila, thianpa nena inbiakna ang maiin.

Hei hi eng nge ni ‘Herd Immunity’?

A awlsam zawngin sawi ila, herd immunity chu hmun emaw pawl emaw a mi tam takin virus emaw, hri kai thei dang emaw laka an him (i.e. venhim) a nih chuan chu natna chu a darh harsa hle a ni. Mi tam tak venhim an nih chuan chu natna hrik chu mi pakhat atanga mi dang a zuang chhuah theihna chance a tlahniam tih han ngaihtuah teh.

Immunity siam dan kawng hrang hrang a awm a:

• Natna leh pianphung anga dam lehna hmangin.
• Vaccine pek hmangin.
• Pawn lam atanga antibodies dawngin, nu atanga naute thleng ang chi (hei hi passive immunity an ti a, chu chu tlem kan sawi leh ang).

Doctor te chuan vaccine hi invenna tha ber leh him ber a ni an ti .

Immune nei apiangin midangte hnena natna a darh loh nan an pui thin. Vaccine pek i ni tawh ang tih han ngaihtuah teh. Chutiang chuan mi dang hnena hri kai darh theihna chance a tlahniam a ni. Tin, i taksa chhunga virus inthlak danglam a, variant thar siam theihna chance a ti tlem bawk. Amaherawhchu, virus a darh chak em em a nih chuan a laka invenna (immune) hi a titawp tur chuan a tam zawk a ngai a ni.

A chang chuan he herd immunity hi ``community immunity'' emaw ``population immunity'' emaw an ti bawk.An awmzia inang vek an ni.

Engtin nge immunity hi a lo awm?

Antibodies hi kan taksain natna thlentu hrik kan taksaa lutte do tura a siam bik thil bik a ni. Antibody tin hian natna pakhat chauh lakah venhimna a pe a ni. He immunity hi kawng lian pahnih hmangin kan hmu thei a ni.

Active Immunity a ni

Hei hian kan taksa atanga antibody siam a huam a ni. Hei hi kawng hnih in a thleng thei bawk:

1. Natural immunity: Chumi awmzia chu kan damloh a, kan dam leh chuan kan taksain chu natna laka antibody a siam tihna a ni.

2. Vaccine lak atanga invenna: Vaccine hmang hian natna hrik chak lo emaw, thi tawh emaw (a nih loh leh a then) kan taksaah luhtir a, chu chuan kan taksain chu natna laka antibody a siam chhuak thin.

He active immunity hian kan taksa hi "immune memory" a pe a ni. Chumi awmzia chu nakin lawkah natna ang chiah hi kan vei leh chuan kan taksain a hre thuai thei a, antibody a siam thei tihna a ni.

Passive Immunity a ni

Hei hi kan taksa pawn lam atanga antibody kan dawn hian a ni. Entir nan:

• Nausen piang tharte hian an nu hnen atangin nu hnute tui hmangin antibody an dawng thin.
• Thisen atanga thil siam thenkhat hmangin antibody kan hmu thei a.

He passive immunity ah hian kan taksa hian chutiang "memory" chu a nei lo. Chuvangin a venhimna chu pawn lam atanga antibody kan dawn hma chauh a ni. Hun eng emaw chen atan a ni.

Herd immunity hi COVID-19 nen engtin nge a inzawm?

`(COVID-19)` virus, a original form, leh a hnu lama variant `(Delta variant)` leh `(Omicron variant)` ang chi te hi engtiang chiahin nge a darh chak tih i hria. Hripui a lo chhuah tirh lamah khan zirchiangtute chuan khawvel mihring 60% atanga 70% velin hri danna an pek emaw, natna atanga dam leh emaw, immunity nei emaw chuan `(COVID-19)` laka herd immunity an siam thei dawn niin an ngai a.

Mahse, zirchiangtute chuan he number hi a tawk lo mai thei tih an hrechhuak a, `(Delta)` leh `(Omicron)` variant te hi a hrik kai theih zia ngaihtuah chuan. Tunah chuan mi thenkhat chuan chu chu 85% vel pawh a ni thei niin an sawi.

Vaccine tel lo chuan COVID-19 laka herd immunity kan nei thei lo em ni?

Dik tak chuan vaccine tel lova ``(COVID-19)`` ang natna laka herd immunity siam hi thil harsa leh hlauhawm tak a ni. Chutiang a nih theih nan chuan mi tam takin he natna hi an kai a ngai dawn a ni. Chutiang a nih chuan mi tam tak an thi ang a, mi tam tak chu na takin an na ang.

Tunah hian vaccine hmang pawh hian herd immunity neih theihna kawngah harsatna engemaw zat a awm a. En teh:

• Mi thenkhat (entir nan, immunity hniam tak tak nei - `(immunocompromised)`) te hian vaccine an lak hnuah pawh antibody an siam tha lo.
• COVID-19 atanga kan dam leh hnu emaw, vaccine kan lak hnuah pawh chu immunity chu eng chen nge a daih tih chiang takin kan la hre lo.
• Khawvela mi zawng zawng hian vaccine inang an dawng vek lo.

A pawimawh ber chu vaccine lak loha herd immunity beisei hi chhiatna lian tak thlen ang a ni.

Measles leh influenza laka herd immunity chungchanga kan zir chhuah

Vaccine hian natna hlauhawm tak tak lakah kan nunna a chhanhim tak zet a ni. Measles hi natna khirh takah kan ngai tawh lo a, mahse khawvel hmun hrang hrangah damdawi lam enkawlna tha awm lohna hmunah chuan measles vei naupang 5% vel an thi thin. United States ang ram, vaccine pek dan pangngaia lo awm tawhah chuan measles vei hi 99% chuang zetin an tlahniam tawh a ni.

Mahse, measles hri leng hi a chang chuan vaccine la lote zingah a awm thin. Entirnan, kum 2019 khan United States-ah measles vei mi 1,282 an awm a, kum 1992 hnu lama hri kai tamna ber a ni a, hri danna la lo, a bik takin ram pawn lama zin tawhte, leh hri danna la nei lo hmuna chengte chu an hlauhawm ber a ni.

Vaccine hian natna hrik inang, measles leh smallpox te lakah herd immunity a siam thei a, mahse influenza ang natna ("flu" kan ti) erawh chu a danglam deuh hlek a ni. Virus chi hrang hrang a awm a, chu chuan flu a thlen thei a ni. Kum tin flu vaccine pek thin hi virus chi tlemte laka siam a ni a, chu kum chuan a hluar ber nia ngaih a ni.

Flu vaccine lak hian thihna a veng thei a, a bik takin naupang zingah thihna a veng thei a ni. Natna nasatzia leh damdawi ina dah ngaina a tiziaawm thei bawk. Kan chhehvela midangte pawh a venghim bawk. Amaherawhchu, heng thil tha zawng zawng karah hian mi tam tak chuan kum tin flu vaccine hi an la lo.
