Gaano Katagal ang Mild Fever Bilang Normal Side Effect ng Flu Vaccine

Ang mild fever pagkatapos ng flu vaccine ay normal na side effect na karaniwang nagsisimula 6-12 oras pagkatapos ng bakuna at tumatagal lamang ng 1-2 araw. 1

Karaniwang Timeline ng Lagnat

Ang systemic reactions tulad ng lagnat ay may predictable na pattern:

  • Simula ng sintomas: Nagsisimula 6-12 oras pagkatapos ng vaccination 1
  • Tagal ng lagnat: Tumatagal ng 1-2 araw lamang 1
  • Karamihan ng mga pasyente (89%) ay gumaling na sa loob ng 1-3 araw 2

Ano ang Dapat Asahan

Ang mga sumusunod ay normal na side effects na hindi dapat ikabahala:

  • Local reactions (sakit sa injection site): Nakakaapekto sa 10-64% ng mga pasyente, tumatagal ng mas mababa sa 2 araw 1
  • Systemic symptoms (lagnat, pagkapagod, pananakit ng katawan): Mas karaniwan sa mga taong walang dating exposure sa influenza virus antigens sa vaccine, tulad ng mga bata 1
  • Ang lagnat ay hindi nangangahulugang may influenza ang pasyente - ang vaccine ay naglalaman lamang ng noninfectious killed viruses at hindi maaaring magdulot ng totoong flu 1, 3

Kailan Dapat Mag-alala

Dapat kumunsulta sa doktor kung:

  • Ang lagnat ay tumatagal ng higit sa 2-3 araw 3
  • May mga senyales ng allergic reaction (hives, pamamaga ng labi o dila, hirap sa paghinga) 1
  • Ang pamamaga sa injection site ay lumalaki pa 3
  • May persistent high fever na hindi bumababa 3

Paggamot ng Mild Fever

Ang mga sumusunod ay maaaring gawin para sa sintomas:

  • Acetaminophen para sa lagnat at discomfort 3, 4
  • Adequate hydration at pahinga 3, 4
  • Cold compress sa injection site kung masakit 3

Mahalagang Paalala

Ang respiratory illness na nangyayari pagkatapos ng vaccination ay madalas na coincidental illness na hindi related sa vaccine mismo 1. Kung ang sintomas ay tumatagal ng higit sa 2 araw o lumalala, dapat magpa-check up para masiguro na hindi ito ibang sakit na nagkataon lang na nangyari pagkatapos ng bakuna 3.

Ang mga benepisyo ng flu vaccine sa pagpigil ng influenza at ang mga komplikasyon nito ay mas malaki kaysa sa panganib ng mild side effects 3.
