Laressa Roberts was told to 'set your child on fire to keep mine warm' and 'f*** off and die' after Isiah, five, was sent to hospital for a week when he caught rotavirus from a schoolfriend

A mother has been told to set her five-year-old son on fire by 'vile' anti-vaccination campaigners.

Laressa Roberts was told to 'set your child on fire to keep mine warm' and 'f*** off and die' after Isiah, five, was sent to hospital for a week when he caught rotavirus from a schoolfriend.

Her son must go to hospital once a month because he gets infections from other children as a result of his inability to have vaccinations.

The youngster, from Jersey Village in Texas, was born with thyroid disease, which means he cannot receive all routine vaccinations due to his compromized immune system.

That includes the jab for rotavirus, which in the US is typically vaccinated against in toddlers.

Receptionist Laressa, 24, took to social media last week to vent her frustration about the importance of vaccinations with a photo of the youngster bedridden in hospital.

But she claims she was hit with an outpouring of vitriol and death threats from hundreds of anti-vaccination campaigners who told her Isiah's illness had been caused by jabs.

Laressa said she decided to go public and share the post documenting Isiah's health battles last week after becoming frustrated her son is hospitalised by bugs and viruses once a month on average. Pictured: Some of the abuse she received

Larissa said: 'I fully support mandatory vaccinations not just because of my son, but because of all other immunocompromised people as well'

Mother-of-one Laressa said: 'I was shocked at the trolling, honestly. I knew people disagreed with vaccines, but I honestly assumed they would come from an educated angle.

'But I have received nothing but a negative response. It's honestly been terrible.

'They have been not just downright abusive towards myself, but towards a child at that.

'It breaks my heart that they feel this way, and they feel the best way to strike out at someone is by harassing them.

'Now Isiah might not be able to attend schooling because he caught a disease he should have been vaccinated for.

'I fully support mandatory vaccinations not just because of my son, but because of all other immunocompromised people as well.'

Laressa claims anti-vaccination campaigners told her she had put her son at more risk by telling other parents to keep their children's jabs up to date

Laressa said she decided to go public and share the post documenting Isiah's health battles last week after becoming frustrated her son is hospitalised by bugs and viruses once a month on average.

The five-year-old has only been able to have certain jabs since he was born, rather than the full set normally given to children in the USA.

Vaccinations in the US - Vaccines prevent dangerous and sometimes deadly diseases - In the USA, children will typically receive vaccinations against a number of diseases including Hepatitis B, Tetanus, Whooping Cough and Rotavirus - However, children born with Thyroid Disease are sometime unable to receive certain vaccinations due to the illness weakening their immune systems - Opposition to vaccines has existed since the first one was introduced against smallpox in 1796 - But side effects are extremely rare and medical professionals globally agree the benefits outweigh the risks Advertisement

Laressa wants to raise awareness not only for her own son's wellbeing but to protect other people who can be put at risk by diseases spread by unvaccinated children.

But she claims anti-vaccination campaigners told her she had put her son at more risk by telling other parents to keep their children's jabs up to date.

Others even blamed his illness, which he was diagnosed with shortly after birth, on the previous vaccinations he was able to have and said he was spreading diseases to other people.

Laressa said: 'I shared Isiah's story because I was venting.. I was frustrated, tired, and felt helpless. No matter how hard myself or his doctor tried, he was getting sick.

'He's having to miss out on basic childhood experiences, I fear even taking him to the park because I don't know what children have been there and if they've been sick.

'There are hundreds of immunocompromised children, adults, cancer sufferers, and even those who aren't able to be vaccinated yet, such as newborns.'
