In Pakistan, vaccination records are kept on computerised national identity cards (CNICs), and anyone who has received vaccinations—full or partial—can request vaccination records. For example, after receiving the single dose immunisation necessary for vaccines like CanSino or PakVac, or after receiving one or both COVID-19 immunizations, passengers travelling domestically or internationally may use these certificates. You can also ask for such a brand at the immunisation clinic if you have to travel to a country that has this restriction. Some countries will only let visitors who have got vaccinations from a particular company, such Pfizer or Astra Zeneca. An official COVID-19 immunisation certificate is now required of all visitors to popular tourist spots in Pakistan. Here is the NADRA Covid Vaccine Registration at imchospital.
