A junior health nurse was attacked at a primary school in Malappuram district by some persons during the state government's ongoing Measles Rubella (MR) vaccination drive, police said.

They said three persons were arrested today in connection with the attack and a case registered against them for non-bailable offences.The nurse was attacked at the school in Edayoor panchayat yesterday by some persons when she was administering the MR vaccine to children.The Kerala government had last month extended the campaign deadline as it did not receive the expected results in some districts due to an anti-vaccination campaign.

Taking a serious view of the incident, Kerala Health minister K K Shylaja today said all the accused would be arrested as early as possible.The DGP had been directed to take stern against those responsible for the incident, she said in a Facebook post.She said there have been instances in the past by a group of people, in a well planned manner, to cause hurdles to the government's vaccination drive. They launch fake campaigns in the social media and corner meetings, she said.However, health department officials have overcome such attempts and the result is that the state has succeeded in keeping serious diseases from its doorsteps, she said.

Protesting against attacks on doctors and nurses at various places,Kerala Government Medical Officers Association (KGMOA) boycotted attending out patients in government hospitals throughout the state from 9 AM-10 AM this morning.Attacks on members of the medical fraternity has been reported from Kozhikode, Kasaragod, Thalassery and Thrissur, and such incidents should be viewed seriously, the KGMOA said.Indian Medical Association state President Dr E K Ummer and secretary, Dr Sulfi said in a statement that IMA would observe a 'black day' throughout the state tomorrow.If stern measures are not taken against those behind such incidents, IMA would be forced to other modes of agitation, he said.
