People in Vientiane and some provinces have now had their first and second doses of the Covid-19 vaccine.
More people have been going to vaccination centres around the country since the programme was launched in March.
The government plans to vaccinate at least 150,000 people in the initial stages of the programme.
Director-General of the Department of Hygiene and Health Promotion under the Ministry of Health, Dr Phonepaseuth Ounaphom, told reporters that the programme was making good progress.
The vaccination drive is part of Covid-19 prevention and control plans which health authorities are going all out to implement in a bid to keep the virus in check.
The vaccination programme has now been expanded to cover more target groups in addition to health workers.
People can register online at health centres in their districts.
Dr Phonepaseuth advised people not to worry about getting the vaccine because there were about one million doses in stock.
The World Health Organisation (WHO) and Unicef have provided technical assistance to develop the national deployment and vaccination plan for Covid-19 vaccines to improve system preparedness and readiness to administer the vaccines.
In collaboration with the Ministry of Health, the United Nations has redesigned the Sexual and Reproductive, Maternal, Newborn, Child, and Adolescent Health Services programme to continue providing essential health services during the pandemic with particular engagement by UNFPA, WHO, Unicef, and UNAIDS. — Vientiane Times/ANN
